Cloud computing is a platform that provides online server services for an individual or a group of clients. The cloud computing services are of four types, namely, SaaS (software as a service), IaaS (infrastructure as a service), PaaS (platform as a service) and MaaS (mobility as a service).
The SaaS is used by web or email services, where the server sends or loads the application data to the client, and all data can be viewed and modified on the copy of the data sent to the client.
